preventing development of allergy>
I'm not sure what you're saying/asking here. [Baby is having intestinal
reactions to cow's milk proteins and that's commonly called allergy,
especially in babies, but others like to save the term for
respiratory/hives type reactions].
I THINK you might be reading studies where mom avoids certain foods
during pregnancy and early lactation in attempt to prevent a child from
developing certain allergies or sensitivities when a family is allergy-
prone. No there's not a lot of luck here (some). BUT, if a child is already
reacting to something then absolutely the child benefits from avoidance
of this food (in mom's milk or otherwise). Their best chance of having
healthy non-inflamed intestines with good absorption of all nutrients is
by not regularly experiencing intestinal reactions to foods (and even
eczema nearly always involves intestinal reactions measurable in
science lab studies) and their best chance for "outgrowing" the
sensitivity is by keeping the inflammation down and the antibody levels
down (avoiding) for a lengthy period of time (that will be different in
every child; maybe a year, maybe two, and a few never outgrow some
food sensitivities).
On the other hand, it's very common for a child who is reacting to cow's
milk proteins to develop other food sensitivities if the reactions go on
for some time. The inflamed & irritated (some say "leaky") intestines
begin allowing other kinds of proteins to pass through the intestinal
wall (milk proteins are designed to pass through intestinal wall and
baby intestines are designed to accept them, human milk proteins that
is) and in a child who has already reacted to CM proteins, other
reactions are likely to develop.
If baby is "sensitive/intolerant" to CM proteins, this seldom converts to
what allergists call true allergy (if that's what's being implied here). It's
all a muddy picture in terms of the word "allergy," as allergists, or peds
using standard allergy tests, will call something an allergy if they find
IgE antibodies (whether it's intestinal or respiratory), and if they don't
find them, they say it's not and allergy (and sometimes infer that the
symptoms can be ignored then). Regardless, if a food that doesn't
bother most people makes someone not feel well, have diarrhea, break
out in rashes, or otherwise sick, it's not pleasant nor healthy (and it's
the original meaning of an allergy) AND the way that allergists often
like to say "It's not an immune reaction" if they don't find IgE
antibodies on blood or scratch tests is such a funny thing because
immunologists and other PhD's studying food reactions know that there
are IgG, IgA, IgM, various interleukins, mast cells and their various
mediators, TGFb, TNF, T cells, and all kinds of Immune System
components that are involved in the various kinds of food reactions that
people have.
